SPECIFICATION forming part of Letters Patent No. 395,883, dated January 8, 1889. Application filed January 28, 1888. fserial No. 262,206. (No model.)

To aZZ whom it may concern.-

Be it known that I, Josn PH FRANKLIN GENT, a citizen of the 'United States, residing at (olumbus, in the ci'mnty of Bartholomew and State of Indiana, have invented certain new and useful Improvements in Machines for Making Sheet and l lalv'c Products from Corcals; and I do hereby declare the fcllowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for pro ducin g a sheet or iialted product from cereals;

and it consists in certain improvements upon the machine. for which Letters Patent No. 347,790 were granted to the August 2-1, 1986.

The peculiar features of cmistruction and combination of parts which constitute my present invention are illustrated in the accompanying drawings, and said invention is fully described in the following specification and claims.

In the drawings, Figure l is a front elevation of my improved nmchine, parts being broken away. Fig. 2 is a cross-scct-itm through one of the side pieces of the main frame of the machine. Fig. I; is :1 section on line :1: .r of Fig. 2. Figs. land are detail views of parts of the machine; and Fig. is a vertical transverse section on line 1 i Fig. .l.

The main frame of the machine consists of the side pieces, A an d A, which are provided with the cap-plates ll and ll, secured thereto by bolts or screws. The side pieces are held firmly 'logellun' by long rods or bolts (1', and the machine may be n-ovided with a baseplate, I), if desired, although this is not esscnt ial, as the side pieces may rest upon the floor. Upon the capplates B and B are.

mounted the vertical standards C C C C,

which supportlhc cylinder I) and trough or receptacle E.

Upon a shaft mounted in-bearin ends of cylinder I) is a cylindrical roller, (1, i

which maybe hollow or solid, as preferred,

and which is provided with projections upon its outer surface, extending nearly to the inner surface of the cylinder D. These projections are arranged spirally upon the cylindrical roller, as will be hereinafter more fully described.' The shaft of the roller a may be l l l 2 l l l l l 1 l l 1 s in the i l l l bear with the proper I provided with suitable band or other pulleys for receiving motion from arunning shaft, as may be found convenient.

Upon its upper outer surface the cylinder D is provided with a funneLshaped receptaclc or hopper, d, discharging into the interior of the cylinder, for the introduction of the crushed or ground cereal, and the cylinder is also provided with two pipes, (1' (1 for the admission of steam and hot water. At the end farthest from the receptacle (1' an aperture, d", is formed in the bottom of the cylinder, which opens into the trough or receptacle E. The receptacle E is in this instance supported by bolts passing through its sides and securing it to the standards C C C J, as shown in Fig. and contains a screw conis provided with a suitable band-pulley. The

curved bottom of this receptacle E is provided with holes or openings 6, as best shown in Fig. 1.

The side pieces of the main frame are provided with openings or recesses F, and larger openings to receive the bearings G of rollers K, L. M, and N. The rollers K and M are mounted the one above the other, and the rollers L and N are also mounted above one another, but in a different vertical plane from the rollers K and I. The roller L comes in contact and bears against rollers K and M, and the latter roller comes in contact with and bears against the rollers L and N, giving three distinct and separate compressions of the material between the four rollers, as shown in the drawings, the first being between K and L, the second between L and M, and the third between M and N. By this means I effect the same number of compressions of the material with four rollers as would be effected by six rollers arranged as shown and described in my former patent. To effect these compressions in the manner desired, it is necessary that the rollers should be adjusted so that each roller shall "orce upon the other or others with which it comes in contact. To accomplish this result, I provide the upper and receive the bearings with recesses to receive the screw-threaded bolts or nuts g. Through apertures which connect the openlower faces of the openings which ings F with the reeesses containing the nuts 1 l)ireetly under the openings in the bottom are passed holts g, provided at one end with r of the reeeptaele lfl isaslantingehute l, (hest serew-threads to engage the threads ol. the seen in it.) whieh direets the nutterial nuts g, and at the other end with square or dropped upon it tothe rollers l\' and l).
